The Principle of Use of Force in Contemporary International Law : Its Situation

本研究从当代国际法的规范制定过程、宪法与国际公法的含义、多边环境协定中的不遵守程序与国际法院的政治问题理论以及战争法与国际安全理论等角度对使用武力原则进行了研究，《联合国宪章》明确规定了源于第一次世界大战的战争违法性，即所有成员国不得以武力相威胁和使用武力。然而，关于使用武力原则的地位及其保障制度的有效性，我们仍有讨论的空间。在这一基本认识的基础上，研究人员在整个研究项目中一直处理着各自感兴趣的问题，到目前为止，IDA教授考虑了国际法的规范及其制定过程。安藤教授从国际合作的国际安全角度评价了日本宪法，并参照日本的态度审议了战争法。Nishii教授仔细研究了多边环境协议中不遵守程序的作用及其未来发展的可能性。此外，杉原教授还重点研究了国际法院的政治问题理论。每个调查员都把自己的工作写成文章。

This research focuses on the principle of use of force from perspectives of the norm making process in contemporary international law, the implication between the constitutional law and public international law, the non-compliance procedure in multilateral environmental agreements and the political issue theory of the International Court of Justice as well as the law of war and the international security theory,The outlawry of war being descended from the First World War has been explicitly ruled in the United Nations Charter in that all members shall refrain from the threat and use of force. Nevertheless, we have a room for discussion concerning the position of the principle of use of force and its effectiveness of securing systems.Sharing this basic recognition, the investigators have dealt with each own interested issue all the way of the research project so far Prof. IDA has considered the norms of international law and its making process. Prof. ANDO has evaluated the Japanese constitutional law on a perspective of international security in the context of international cooperation and has considered the law of war with reference to the Japanese attitudes. Prof. NISHII has scrutinized the role of the non-compliance procedures in multilateral environmental agreements and its possibility of future development. Furthermore, Prof. SUGIHARA has focused on the political issue theory in the International Court of Justice. Each investigator has made up his work into articles.
